Zheng (U Mich), report on behalf of the ROTSE\ncollaboration:\n\nDue to bad weather conditions, the ROTSE-3a telescope at Siding Springs\nObservatory, Australia did not respond to GRB 100901A (Swift trigger\n433065, \nImmler S. et al., GCN 11159). Automated re-pointing of ROTSE-3c at the\nH.E.S.S. site at Mt. Gamsberg, Namibia and ROTSE-3b at the McDonald\nObservatory, Texas observed the optical afterglow starting ~ 8.6 to 22.0\nhours after the burst. \nThe optical afterglow was detected in all the stacked frames. The optical \nafterglow candidate appears to decay with a power-law index of ~1.2 at\nlater epochs. Further imaging is ongoing.",
